thankyou.

You're so fluent in English....! Don't mislead the buyers. I'm not a so called fanboy of Sony or Samsung.samsung using medicore GPU (Adreno 203)& modest cpu named Cortex A5. It is the oldest architecture available right now at this market. It is used for Samsung galaxy core, but @the other side Sony Xperia M is equipped with Krait CPU( same as Lumia 1020,920,820,720,620,520,HTC 8x,8s,Xperia L) with Adreno 305 GPU. And for everyone's information about GPU. Yes it is the most important part of Smartphone right now.all 3D games are depends on the power of the GPU, Without a GPU a simple live wallpaper will lag for sure. And the shitty galaxy core can record and play only VGA(480p) videos. It doesn't support HD(720p) AND FULL HD(1080p) VIDEOS. Xperia M support 720p recording and 1080p full HD playback. A single Andero 305 is almost 3* Adreno 203, and a Krait is almost almost 5 times better than a Cortex A5 core.

i have planed to buy a new phone.but now i confuse. "galaxy core duos / xperia m" .which one is better for long time use.in this both phones every specifications are similar ,but only one doubt is internal memmory.
so,kindly help me..its urgent

Don't worry, I brought many items through ebay,moreover if u r living in a city it would be very convenient for u also...I am waiting for my mobile as u r now, I live at a developing village so it may take few more days to get it...

this gud mob for normal use it can't use for hd games bez this mobile hv full touch once lag means u wnt to remove barrty an Thn the processor is 1ghz dual-core oly mob hv normal speed oly barrty backup is very low an screen also normal oly whn we compare to galaxy core is gud its hv big screen 1.2ghz dual-core 50% more barrty compare xperia m Thn graphic is low compare xperia m but graphic is use for mobile colour not for games Thn nfc is not in galaxy core hv in xperia m so this diff
